Application filed June 5,1906. Serial No. 320,294.

To all w/wm it 1na, c01'.iea'i"n:

Be it known that 1, Josnrn Snnnwoon, a; citizen of the United States, and a resident of Lake, in the county of Fremont and State of V certain new and use'lul 1 Improvements in Auto Snow-Gal's, ol' which Idaho, have made the following is a specification.

My invention in is the nature of a car or i sled for use on snow with a propeller for moving the same; and the invention consists in i certain novel constructions and coinhinations of parts as will he hereinafter descrihed and claimed.

in the drawings, Figure 1 is tion; and Figs. 3, t and 5 are detail sections on, respectively, lines 35 3, Fig. 1, 4 l of Fig. 3, and 5 5 of Fig. 1.

In carrying out my invention, i provide a main frame mounted on runners and carrypeller conn cted with the said main frame and arranged to'he operated h v the motor pivoted at their front ends relatively to the main frame and are connected with the exhaust discharge of the engine and deliver mechanism on the main frame to advance the car, andalso to he heated from the said motor anechanism, whcrehy to keep the surface of the propeller clear of accunmlations of snow, sc t will he in operative condition at all times when desired.

In caruving out my invention. the main frame A may he formed with the side heams A, the front cross-liar A. the rear cross-har A, and the intermediate cross--hars A", A, and A, the hars A" "and A supporting the motor 13, which motormay he of any suitahle type, preferahlv a gasolene-enginc, a conventional illustration of the same heing presented i in Figs. 1 and 2 of the drawings. 'l hisengine has a drive-sh: ft l3, a fly-wheel B" thereon,

and has its exhaust fllfit'llul'gillfl to a pipe (i. As the engine inav he of an suitahlc construction well known to those skilled in the art, a detail illustration of same does not appear to he necessarv herein. The .main

frame.. is mounted on the runners l) aml li,

which may he arranged one in advance of the other and may he made of like material on the plan of skees. and the front runners l) are v he turned, h v the supported so thev ma v steering-lever l) to guide the machine.

l.)rive-wheels E are secured on a shaft 1 I wheel and ournaled to the main frame adjacent to the mg a suitahle motor, together with a pro- 5 1 not stick to it, the propeller heing made i the form of a hollow drum, as before demav he ad'nsted u and down in uides if. i 4, i F7 I connected with the main frame hy means of the lovers ll and i. The lever ll pivoted at ll to the main frame connects at its iront end with the shaft l, and has its rear end geared at ll with the front end of the lever l, which lever l is pivoted at l to the main frame and may he operated at its rear end to raise or lower the front propellers E. .Ylien in the position shown in Fig. 1, the lever l secures the front propellers in. position to engage the snow or ice, these propellers I heing especially designed for use in case the V a side view, and Fig. 2 is a top plan view, partly hroken 1 away, or an apparatus emhodymg my inven- Y main propeller should hecome ineffective, such as when crossing ice or the like. A rack i may he provided for engagen'ient hy the lever l in order to hold the front propeller in. an desired adjustment up or down. The rear propeller J is in the form of a eylindriiail drum provided on its periphery with rihs or teeth .1, adapted to engage snow in order to propel the machine forward when operated as presently described, and this drum J is -arricd hr the tnhnlar side hars ii, which are such discharge to the interior of the propeller J, whcrchv to heat the same, so the snow will in scrihcd. in the construction shown the tuhular side hars hi connect at their front ends with a cross-pipe K, (see l igs. 3 and 4,) to which the exhaust-pipe (J discharges at a point midway hctween the ends of the pipe Ii, so the exhaust map circulate through the pipes K and K to the propeller. The crosspipc K is mounted on and the-pipes K are connected h v suitahle swivcl-couplings with ln'anchesli", depending from the pipe ii", the pipes 1Q connecting with the outer ends of a counter-shaft driven h v the sprockM-clurin [J from the engine-shaft ll aml provided with the sprocket-wheels M connected hy the 5 chains M with the sprocket-wheels M on the main, propeller for driving the latter.

ln order to put any desired pressure on the propeller l, 1 provide means hctween the same and themain frame for depressing the said propeller. As shown, the depressing means comprise a shaft X, having a handand provided with a drum X", on which cahles 3 are wound, the said cahles heing suitably guided at Iv and extending hack helow i ends of said tubular side bars and connnunirights E of the rear runners and has the guide-pulleys N at the rear end of the main frame, and thence up and connected at N with the propeller-frame, so that the shaft N may be turned to depress the said propellerframe and the propeller to any desired deree.

g A brake-shaft O is journaled to the updownwardly-projecting shoes 0 and an upwardly-proiecting crank 0 the latter being connected y a pitman O with a treadle O", which may be operated to force the shoes 0 down against the surface of the snow whenever it is desired to brake the machine.

The front propellers may be used as supplemental to the rear or main propeller, but they are specially designed for use in emergencies, as when the machine crosses ice or the like, when the front propellers may be utilized to move the machine until the main propeller may again operate.

It will be noticed that the weight of the main propeller is supported independently of the main frame, so it may operate to propel the machine, and the main frame being relieved of its weigl'it may be utilized'fer carrying a load as may be desired.

1. The combination substantially as herein described ,of the mainframe, the main propeller, the propeller-frame having tubular side bars to which the main propeller is journa'led, a cross-tube connected with the front Jating therewith, a cross-shaft gearing; between said cross-shaft and the propeller drum, an engine on the main frame, gearing between sairl engine and the said cross-shaft, whereby to drive the latter, and means for discharging; the exhaust from the said engine to the cross-tube, whereby it may as delivered thence to the main propeller, substantially as set forth.

ends with bearings for the propeller, an engine on the main frame for driving the propeller, and means for delivering the exhaust from the engine to the saidtubula-r side bars, whereby it ma y be conducted to the propeller, substantially as set forth. 1

3. The combii'iation with the main frame, an engine on the main frame, a cross-shaft geared with the engine, whereby it may be side bars connected with said cross-shaft, the propeller journaled to the tubular side bars, gearing between the propeller and the cross-shaft, and means for delivering the exhaust from the engine to said tubular side bars, substantially as set forth. i.

4. In a machine substantially as described, the combination with the main frame and the runners supporting the same, of a propeller having a cross-shat t and the Wheels secured thereon, a pair of levers pivoted to the main frame and connected at their front ends with the said cross shaft, and extended in rear of their pivots, and operating-levers geared with the rear extension of said levers, substantially as set forth.

5. The combination with the main frame, its supporting runners, and the main propeller, of the propellerdrame ivoted to the main frame and to which the main propeller is journale'dya shaft journal'ed to the main frame, cables operated by said shaft, and connected with thev ropeller-frame, and guides for said cables elowthe connection ofthe cableswith the propeller-frame whereby they may operate to depressthe propeller I frame, substantially as set forth.
